SFP controller enables low-cost digital video

Maxim Integrated Products is rolling out the DS1877 SFP video controller with a dual-receiver interface that controls and monitors all receiver functions for SFP and SFP+ optical modules and fully supports the SFF-8472 specification.

The DS1877 controls dual-receiver SFP modules and enables the low-cost implementation of SDI digital video and other optical video applications. Its state-machine approach eliminates the need for expensive microcontrollers and, in turn, avoids the costly software development they require. Paired with the DS1876 (an SFP controller with dual laser driver interface), the DS1877 enables full-featured optical video modules at a fraction of the cost of microcontroller-based designs.

The DS1877 monitors four analog channels: temperature, Vcc, and two external differential signals. Loss of signal (LOS) is continuously monitored in both receiver channels, and all LOS functionality is supported.

The DS1877 is fully specified over the -40°C to +95°C temperature range, and is available in a 5mm x 5mm, 28-pin TQFN package. Pricing starts at $1.75 (1,000-up, FOB USA).
